摘要:

将二维机织碳布和单向碳布预浸料按照一定比例铺设成的混合机织复合材料兼具比刚度、比强度高、抗低速冲击损伤以及工艺性好等优点。本文试验研究了三个铺层结构相似,但总厚度不同的混合机织复合材料的低速冲击性能,采用超声波C扫描法记录了各层合板损伤面积,测量了剩余压缩强度,并进行了准静态横向压缩试验。通过试验分析本文认为,厚度增加会使层合板内部的超声波C扫描损伤面积增加,但并不会明显影响其剩余压缩强度。

Abstract:

The mixed woven composites being laid up by 2D woven and unidirectional carbon prepreg alternately have the advantages of special stiffness, special strength and impact performance, and the processibility is good also. In this paper, three types laminates of similar stacking structure but be different in thickness were investigated.
